Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pressing shaving board, directional shaving board, finishable shaving board, especially the cylinder glue mixer for shaving material in the pressing shaving board. BACKGROUND

[0002] Before pressing shaving board (or pressing directional shaving board, finishable shaving board), usually need to be shaved material (the size of the original wood is not the same size piece of material), then need to have glue (MDI / urea formaldehyde glue) and shaving material mixing stirring. Because the glue is high viscosity material, if you want to achieve full mixing and stirring, the current way is basically to spray glue on the shaving material.

[0003] At present, this kind of equipment basically adopts the design idea of Europe and the United States, that is, to use centrifugal sprayer. The advantages of this design are: 1. By adjusting the speed of centrifugal disc, the spraying amount can be easily changed, so as to control the spraying of glue on the shaving material, and the spraying effect can be effectively controlled; 2. Because the glue is high viscosity material, it will not be blocked.

[0004] However, the above design idea also has some defects: 1. This kind of centrifugal atomizer is 6000~15000r / min, and needs to run 7600~8000 hours every year, which leads to short service life and needs to be replaced regularly, thus causing cost soaring; 2. Because it is high-speed rotating and has built-in power supply, and the shaving material has dust, it is easy to cause fire and even explosion; 3. Moreover, after the atomizer stops working, the atomizer will still drip glue, which will cause excess adhesive and affect the quality of the subsequent pressed board.

[0005] Therefore, based on the defects of the existing design, the company designs a new cylinder glue mixer for shaving material under the entrustment of the customer. SUMMARY

[0006] The utility model discloses a cylinder glue mixer for shaving material in the pressing shaving board, which overcomes the defects of the prior art and solves the problems of high cost, low safety and inconvenient adjustment of the nozzle position.

[0019] As a preferred technical scheme of the present application, the compressed gas is compressed nitrogen gas, so that the oxygen content in the drum mixer is less than 5%.

[0020] As a preferred technical scheme of the present application, a triangular passage cylinder is arranged in parallel with the axial direction at the middle upper part of the drum cavity of the drum, a rectangular pipe is arranged in the triangular passage cylinder, and each pipeline is arranged on the side wall of the triangular passage cylinder. A plurality of notches are formed in the bottom wall of the triangular passage cylinder, and the nozzle part of the compressed gas atomizing nozzle on the rectangular pipe extends downward from the notches.

[0021] Secondly, on the basis of the design of the drum mixer for flake material in the pressed flake board, other designs are also made. The bottom plate of the rectangular pipe is provided with a long groove, so that the cross section of the rectangular pipe is in the shape of C with the opening downward; a vertical rod is fixed on the central pipe of the compressed gas atomizing nozzle, and the vertical rod has a protrusion near the upper end; the upper end of the vertical rod is inserted into the rectangular pipe through the long groove, and at this time, the protrusion is abutted against the lower surface of the bottom plate of the rectangular pipe; and after a pressing block is sleeved on the upper end of the vertical rod and is fastened by a nut, the pressing block is pressed against the upper surface of the bottom plate of the rectangular pipe.

[0022] Further, according to the need, the following design can be made: the upper surface of the protrusion is provided with a roller A, and the lower surface of the pressing plate is provided with a roller B; when the protrusion and the pressing plate are pressed against the bottom plate of the rectangular pipe, the bottom plate is abutted against by the corresponding roller A and roller B, so that the structure that the compressed gas atomizing nozzle can be adjusted in the parallel axial position is formed.

By pulling the positions of the thin ropes, the positions of the compressed gas atomizing nozzles can be adjusted.

[0023] The present application has the following advantages:

[0024] (1) The service life of the equipment can be improved, and the cost can be greatly reduced; and through the design of the pipeline, the spray amount can also be accurately controlled;

[0025] In the field of shaving material pressing plate, centrifugal atomizer is used in the roller glue mixing roller, the rotating speed is 6000-15000r / min, it needs to run 7600-8000 hours per year, which leads to short service life and needs to be replaced regularly, and then the cost rises;

[0026] In the scheme, the compressed gas atomizing nozzle is provided, which is basically not subject to wear and tear and can be used for a long time, thereby improving the service life of the equipment and reducing the cost of equipment replacement; in addition, in such compressed gas atomizing nozzles, the most difficult to control is the accurate amount of each component, so through the design of the pipeline, the spray amount of the atomizing nozzle can be accurately controlled, thereby achieving the same effect as the centrifugal atomizing nozzle; (some existing companies may have technical personnel who think of using air compression atomizing nozzles, but in actual experiments, it is difficult to accurately control the amount of each nozzle, thereby leading to poor final spraying effect, so companies on the market have given up this design; in the scheme, the material is introduced into the corresponding tank, and then an air compression source is used for extrusion, the air pressure in the tank is adjusted before extrusion, the pressure in the tank is consistent each time, the material extruded from each pipe is consistent each time, and the material extruded from each pipe tends to be consistent after multiple extrusions, so only a certain period of debugging is needed to achieve accurate spray amount of the atomizing nozzle, thereby ensuring the spraying effect)

[0027] (2) Avoid dust explosion in the roller, improve safety;

[0028] In the field of shaving material plate production, centrifugal atomizer is used in the roller glue mixing roller, which is high-speed rotating and has an internal power supply, and the shaving material has dust, so it is easy to cause fire and even explosion;

[0029] In the scheme, the compressed gas atomizing nozzle is used, all pipelines are led out of the roller, and there is no electrical element in the roller, so explosion due to ignition of dust is impossible;

[0030] (3) Avoid the residual glue of the nozzle from dropping and affecting the subsequent shaving material pressing plate effect;

[0031] In the existing centrifugal atomizer, after the atomizer stops working, the atomizer still drips glue, thereby causing excess adhesive, which affects the quality of the subsequent pressed plate;

[0032] The compressed gas atomizing nozzle used in the scheme is sprayed by compressed gas, so it is basically impossible to accumulate glue liquid at the atomizing nozzle after compression and shutdown, so there is no excess adhesive in the subsequent shaving material;

[0033] (4) By pulling the string outside the roller, the position of the compressed gas atomizing nozzle can be adjusted, and when the atomizing effect is poor, the position of the compressed gas atomizing nozzle can be adjusted to adjust the spraying effect.

[0034] (5) The nozzle is arranged in a rhombic structure, and compared with the cylindrical structure adopted by the European and American roller rubber mixing machine, the surface area of the rhombic structure is reduced, so that the shavings are hung or adhered on the outer wall to the maximum extent, and the nozzle is prevented from being blocked and the maintenance time is reduced.

[0035] (6) The compressed gas used in the scheme is compressed nitrogen, so that the oxygen content in the roller rubber mixing machine is less than 5%, and the static electricity generated by the friction between the shavings during the mixing process is avoided to cause dust explosion.

[0064] (Second aspect)

[0065] On the basis of the structure of the first aspect, the following design is made.

[0066] Referring to Figure 8 and Figure 9, the bottom plate of the rectangular tube 40 is provided with a long slot, so that the cross section of the rectangular tube 40 is in the shape of C with the opening facing downward. The vertical rod is fixed on the center tube 21 of the compressed gas atomizing nozzle 20, and the vertical rod is provided with a protrusion near the upper end. During installation, the upper end of the vertical rod is inserted into the rectangular tube 40 through the long slot, and the protrusion is abutted against the eighth lower surface of the rectangular tube 40, then the pressing plate is sleeved on the end of the vertical rod inserted into the long slot, and the nut is screwed, so that the protrusion and the pressing plate are clamped on the bottom plate of the rectangular tube 40 to be fixed.

[0067] According to the needs, the compressed gas atomizing nozzle 20 in the embodiment can also be designed as follows.

[0068] The pressing block is provided with a roller A on the upper surface of the protrusion and a roller B on the lower surface of the pressing block. In addition, the lengths of the vertical rods of the compressed gas atomizing nozzles 20 inserted into the rod head of the rectangular tube 40 are different; the uppermost end of the rod head is provided with a hole, and two thin ropes are bound in the hole and are fixed after being drawn out from the left and right directions along the two ends of the rectangular tube 40 to the roller 10.

[0069] During installation, the compressed gas atomizing nozzle 20 is installed from one end of the rectangular tube 40, so that the vertical rod part between the protrusion and the pressing block is clamped in the long slot, and the roller A and the roller B are abutted against the upper surface and the lower surface of the bottom plate of the rectangular tube 40, respectively, then the nut is screwed on the end of the vertical rod, and the nut is pressed on the pressing block, so that the installation is fixed and locked (in addition, since the compressed gas atomizing nozzle 20 will inevitably vibrate during atomizing spraying, the roller A and the roller B are made of rubber rollers with slight elasticity, and the nut is tightened).

[0070] During work, when it is observed that the spraying effect is not very ideal, the position of the compressed gas atomizing nozzle 20 can be adjusted by pulling the thin ropes outside the roller (for example, when it is needed to adjust the position of the corresponding nozzle to the left, the right thin rope is loosened, the left thin rope is pulled to the left, and then the two thin ropes are fixed), and the friction during adjustment is reduced through the corresponding roller A and roller B (of course, there are many other ways to adjust the position of the compressed gas atomizing nozzle 20, and this way has very low cost, and any way that can simply adjust the position of the compressed gas atomizing nozzle 20 outside the roller is within the protection scope of the present scheme).

[0071] The roller glue mixer for fluff material in the pressed flake board in the first aspect and the second aspect will be further described below.

[0072] In this embodiment, the compressed gas atomizing nozzles 20 near the right end of the roller 10 are connected to the paraffin emulsion constant pressure flow distributor III during pipeline connection, and the compressed gas atomizing nozzles 20 in the middle and left end of the roller 10 are connected to the curing agent constant pressure flow distributor III. When the material enters, the paraffin emulsion is sprayed first, and then the curing agent is sprayed.

[0073] It should be noted that the scheme works:

[0074] The material is introduced into the corresponding tank, and then an air compression source is used for extrusion. The air pressure in the tank is adjusted before extrusion, and the pressure in the tank is consistent each time. In this way, the material extruded from each pipe is consistent each time, and the material in each pipe tends to be consistent after multiple extrusions. In this way, only a certain amount of time is needed for adjustment to achieve accurate spraying of the atomizing nozzle, thereby ensuring the spraying effect.

[0075] In addition, by taking photos to observe the actual atomization effect, the position of the compressed gas atomizing nozzle 20 in the left and right directions of the roller 10 can be adjusted conveniently through a pull rope, avoiding the traditional form of disassembling the roller and then adjusting, and the adjustment is convenient.

[0076] The above embodiments only express the preferred embodiments, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
